Look at the vtkDataArray class.  There are many functions that let you
find what data values are in the array.  Under VTK 4.x you could use
something like so (Python example):

arr = vtkFloatArray()
# add elements to the array
# ...
# now print them
n = arr.GetNumberOfTuples()
for i in range(n):
    print arr.GetValue(i)
